This document contains solutions to three equations involving fractions equal to values.
The first equation, x^2 + x - 2 = 0, is solved to find the values of x that satisfy the equation, which are x = 1 and x = -2.
The second equation, (x-1)/(x+1) = 3, is solved to find the value of x that makes the fraction equal to 3, which is x = -2.
The third equation, x/(x-1) - 1/(x+2) - 3/(x-1)(x+2) = 0, is solved but does not have any real number solutions for x.
2. Neneigiamasis skai?ius b ¡Ý 0, kuriam yra
teisinga lygyb? b n = a , vadinamas
aritmetine n -ojo laipsnio ?aknimi i? a .
a ¡Ý 0, o n ¡Ý 2 ¨C lyginis nat¨±ralusis
skai?ius.
?ymime

n
a ¨C n -ojo laipsnio ?aknies po?aknis,
b ¨C n -ojo laipsnio ?aknies reik?m?.
3. Pvz.:
16 = 4, (n = 2), nes 4 2 = 16 ir 4 > 0;

81 = 3, (n = 4), nes 34 = 81 ir 3 > 0;
64 = 2, (n = 6), nes 26 = 64 ir 2 > 0.
Lyginio laipsnio ?aknis su neigiamuoju
po?akniu neturi prasm?s.
Pvz.:

n ¡Ý 3 ¨C nelyginis nat¨±ralusis skai?ius.
Skai?ius b (jo ?enklas sutampa su a
?enklu), kuriam yra teisinga lygyb? b n =
